Integrated torque converters and assemblies
View Patent ↗More efficient, economic vehicular torque converters comprising novel integrated one-piece turbine/impeller blade-core assemblies with innovative fluid coupling means for greater torque capacities.
1. A torque converter blade comprising a generally crescent shaped blade body having an outer convex edge, an inner concave edge, a truncated core engaged to said inner concave edge of said blade body to form a torque converter blade segment, and at least one tab for engagement with a torque converter shell, wherein said truncated core of said torque converter blade segment is incurved and comprises means for effecting fluid coupling.
2. The torque converter blade according to claim 1 , wherein said means for effecting fluid coupling by said torque converter blade segment comprises a baffle member.
3. The torque converter blade according to claim 2 , wherein said baffle member is positioned in said incurved area of said torque converter blade segment and is integral therewith.
4. A torque converter turbine comprising a plurality of torque converter blade segments according to claim 1 , wherein adjacent segments are adjoined through their truncated cores to form a turbine core ring.
5. A torque converter pump comprising a plurality of torque converter blades according to claim 1 , wherein adjacent segments are adjoined through their truncated cores to form a pump core ring.
6. A torque converter comprising at least a turbine assembly and a converter pump, said turbine assembly and converter pump comprising:
a plurality of pump blade segments, each pump blade segment including a generally crescent shaped blade body portion with outer and inner convex edges, and a core portion engaged to said inner concave edge of said blade body, wherein the plurality of pump blade segments are joined through the core portions for the plurality of pump blade segments to form a pump core ring;
a plurality of turbine blade segments, each turbine blade segment including a generally crescent shaped blade body portion with outer and inner convex edges, and a core portion engaged to said inner concave edge of said blade body, wherein the plurality of turbine blade segments are joined through the core portions for the plurality of turbine blade segments to form a turbine core ring; and,
a plurality of fluid coupling elements, wherein each fluid coupling element is connected to only one of a core portion from the plurality of pump blade segments or a core portion from the plurality of turbine blade segments and wherein each core portion from the plurality of pump blade and turbine blade segments is connected to a respective fluid coupling element or wherein less than all of the core portions from the plurality of pump blade and turbine blade segments are connected to respective fluid coupling elements.
7. The torque converter according to claim 6 , wherein said truncated cores of said blade segments are incurved and comprise means for effecting fluid coupling.
8. The torque converter according to claim 7 , wherein said means for effecting fluid coupling comprises a baffle member.
9. The torque converter according to claim 8 , wherein said baffle member is positioned in said incurved area and is integral therewith.
